Kettlebell sport (KBs) is increasingly popular, but very few studies have been focused on this discipline. This research aims to investigate the effects of KBs on body composition, strength symmetry, and segmental body composition symmetry in a sample of Italian elite athletes. Data were collected from a sample of 16 athletes of both sexes (11 men and 5 women; 34.5 ± 9.0 years of age). Anthropometric (height, weight, arm, thigh, calf, and waist circumferences), hand grip strength, and total and segmental bioelectrical variables were taken. Body composition was analysed by using bioelectrical impedance vector analysis (BIVA). Paired -tests and confidence ellipses were applied to analyse bilateral differences. Elite athletes of both sexes showed high values of phase angle, indicative of high body cell mass and quality and proxy of muscle mass. Hand grip strength and body composition were symmetrical, with the only exception of a higher %FM in the right leg (Zsp: t = 3.556; = 0.003). In conclusion, this study suggests that KBs contributes to muscle mass improvement, body composition, and strength symmetry, especially in the upper body.
壶铃运动越来越受欢迎，但针对该项目的研究却非常少。本研究旨在调查壶铃运动对意大利精英运动员样本的身体成分、力量对称性和身体各部分成分对称性的影响。研究数据来自16名男女运动员（11名男性和5名女性；年龄34.5±9.0岁）的样本。测量了人体测量学指标（身高、体重、手臂、大腿、小腿和腰围）、握力以及全身和各部分的生物电变量。采用生物电阻抗矢量分析（BIVA）来分析身体成分。应用配对t检验和置信椭圆来分析双侧差异。男女精英运动员的相位角值都很高，表明身体细胞质量高、质量好，是肌肉量的代表指标。握力和身体成分是对称的，唯一的例外是右腿的体脂百分比更高（Zsp：t = 3.556；p = 0.003）。总之，本研究表明壶铃运动有助于增加肌肉量、改善身体成分和力量对称性，尤其是上半身。
